G0775611 H NA B1.11F
G0775611 J Sept.
2001
(See Note 1)
B1.11G
The following problem has been fixed.
!
Black developer initialization fails because
toner is mistakenly supplied due to software
bug, causing SC370 (Developer
Initialization Error – Black). This happens
when performing only the black developer
initialization. (If performing the developer
initialization for black and other color(s)
simultaneously, this problem does not
occur.)
!
If the main switch is tuned off and on, the
SC code is reset and the machine re-starts
the developer initialization. In the worst
case, toner flows out from development unit
(the entrance area where toner is supplied)
to the inside of machine.
!
A fusing clutch has been added to
maximize the life of the fusing unit and oil
supply unit. This firmware version was
temporarily installed in production machines
to keep the clutch constantly moving, until
the clutch control program could be added
to the next version (1.15E).
NOTE: Therefore this version has not been
released.
G0775621 NA B1.11H
NOTE 1 - Engine main firmware version B1.11G
has been implemented from September 25th
production run. The machines with Ver. B1.11F or
older have been reworked in local: However,
some machines have been released to the market
without modification. So, please make sure that
the version of the engine main firmware is
“B1.11G” at installation or next visit. If not, please
update it to “B1.11G” or later.
